CJC-1295 DAC (5 mg Vial)

CJC-1295 DAC is a long-acting synthetic analog of growth hormone-releasing hormone (GHRH). The DAC (Drug Affinity Complex) modification binds reversibly to albumin, extending the peptide’s half-life to approximately 6–8 days. By stimulating pituitary GHRH receptors, CJC-1295 DAC increases GH secretion and circulating IGF-1 in a dose-dependent manner. This educational protocol presents a twice-weekly subcutaneous approach using a practical dilution for clear insulin-syringe measurements.

Dose
1–2 mg per week
Frequency
Once weekly
Timing
Before bed
Duration
8–12 weeks minimum

Long-acting GH secretagogue. Provides sustained GH elevation. Often combined with Ipamorelin.
